Abstract
A smart load center panel (10) accepts two hot legs from each of two power sources, and selectively connects each of a plurality of breakers to one of the two power sources under processor control. A dielectric chassis (12) provides structural support and electrical isolation for a plurality of individual circuit boards (28), each including a pair of breaker stabs (26) and a relay (24) operative to selectively connect each breaker stab (26) to a different power source. A bus bar assembly (20) comprises two bus bars for the hot legs of each of two power sources, and insulates the bus bars from each other and from inadvertent contact. A master printed circuit board (40) comprises slits (43, 45) defining the individual circuit board (28) except at the edges. After mounting and soldering, the edges are cut away, yielding a plurality of individual circuit boards (28). Neutral and ground bus bars (46, 52) are mounted to the side of the panel housing (12), behind a flange of a front opening.
